at least one elongated claw located on the said from that of the firstclaw and are separated from the latter by a distance at least equal tothe height of thehigh'est of the threeclaws; the body and the clawsbeing made of a single piece of metal.

On the annexed drawing is shown, by way of example, one example of theshoe-nail, wherein Fig. l is a front view.

Fig. 2 is a cross section on line 11 11 of Fig. 3.

Fig. 3 is a view from below. r

Fig. 4 relates to a detail.

The example shown is disposed on one of the sides of the sole 1) and ismade of one piece of metal, of hardened steel for example, and in planhaving the general shape of a T. The medium branch 0 is trapezoidal inshape and has on each of its oblique sides a claw d or 2 almost at rightangles with the branch 0 and directed downwardly; in each claw are cutout two large notches 9 thus, creating three teeth 7. The two parts71,2, of the transverse branch h-i each bear on their exterior edge aclaw y or it which is almost perpendicular to the part it or i, directeddownwardly, and in which are cut out two large notches I, thus creatingthree teeth m. Seen from above, the claws d, e, on the one hand, and theclaws 7', k, on the other, are thus very difierently directed and arealmost at right angles to aneanother.

Moreover the claws d, e diverge slightly from the exterior of the soleto the interior, as they are on the oblique sides of the branch 0.

Seen from the side, the branches 0, h, 2' are curved with a convexitywhich is turned downwards and which enables the branches to em- 45.brace the convexity of the sole 2;. The exterior edge of the branch hiand the claws 7, it have likewise, seen from above, a curve enablingthem to embrace in a general manner the curve of the edge of the sole b.1 The claws d, e are not so high as the claws 9' or It, so that theteeth of the different claws may be approximately of the same height.The minimum distances between the claws of different directions aregreater than the heights of the different claws. In the same way theminimum distance between the two claws d,

e'is greater than theheight of each of the latter.

Between the two claws 2c there-is a paw n directed upwards, rising alongthe sole b and having at the top of the latter a hook 0 bearing on theupper surface of thesole b.

The fixation of the example shown, to the sole 1) is eiiected by meansof staples 2 which before use are 'U-shaped, andthe lateral branches ofwhich are. parallel. The latter are striated at 4 and are beveled at 5at their free ends according to planes diverging from the median branch6. To fasten the shoe-nail or tip to the boot, the lateral branches 3 ofthestaples 2 are passed through holes I of the body a and of hook o ofthe tip, then force is exerted on'their transverse "from coming out ofthe sole under the' action of the forces to which the staplesare-subjected. Theholesfi, provided in the body are almostpe'rependicular to those bodies, while the holes 1 made in the hook o ofthepaw n are oblique relative to the latter sothat the staples penetrateinto the sole 1) and their branches 3 run no risk of coming out on theedge of the sole owing to bad direction of driving. v I Grooves H] ofmore or lessdepth are provided in the exterior surfaces of the body aand hook 0, end perpendicularly in the complementary grooves 9, and formpassages enabling the point of a tool to be inserted under thetransverse branch 6 of the staples 2 in order to extract the latter.

The height of the claws d, e increases from the middle of the sole tothe lateral edge of the latter so that the tops of the teeth must bealmost on a rectilinear lineparallel to the ground, in

other words at the same height. The said line joining the tops of theteeth can also have any other desired contour.

Examination of the drawing will show that the shoe-nail or tip is veryfirmly fixed to the sole by means of the staples 2 and the paw n, it iskept in place in the required position by the staples 2 and the paw ndespite the large forces to which it is subjected, it is howeverfastened to the sole 1) only at its median part so that the parts 71., zof its transverse branch can adapt themselves to a certain extent to theground. The claws d,.e and 7', k of the tip penetrate into the groundin-quite different directions and this claws j, k grasp the groundon theedge of the sole 1), while the claws d, e are sufficiently removed bothfrom each other and from the claws 7', k that they do not prevent oneanother from taking a good hold inthe ground. The slight divergence inthe .claws'd, e allows the earth and/or the stones, which might bemomentarily caught in them, to come out easily, while the claws 7', kprotect theunder edge of this sole and the paw n protects the edge ofthe sole. The shoe-nail may be fixed to the heel aswel as tothe sole ofthe boot, and the number of nails used on the boots may vary. 7

WhatIclaim is: l. A shoe-nail for mountain boots, comprising in,combination, a body having the general shape of a T adapted to be placedunder I the sole. of the boot on the edge of the latten'and' thetransverse branch of which embraces in a general manner the contour ofsaid edge, at least one elongated claw located on said transverse branchtwo elongated claws located on the longitudinal branch of said body' andconsequently having quite different directions from'that of said firstclaw, and being separated both from the latter and-'from each other by adistance at least equal't'o the height of the highest of the threeclaws, a fixing paw adapted to pass along the edge of the sole andprovided with a hook bearing onthe upper sur- .face of said sole andhaving'at leastone pair or" holes adapted to receive the lateralbranches of a U-shaped aflixing staplelwhich penetrate into the sole,the holesbeing oblique relative to the hook so that the lateral branchesmay readily enter the interior of the sole, while the transverse branchrests on the shoe-nail, the body,'claws, paw and hook being madeofafsingle piece of metal. a I

2. A shoe-nail for mountain boots, comprising in combination, a bodywhich has the general shape of a T, intended to be placed under the soleof the boot on the edge of the latter, and the transverse branch ofwhich embraces in ageneral staple, the lateral branches of whichpenetrate into the sole, and being provided with a groove between theholes of a pair of holes so that the transverse branch of the staple canbe at least partially received in said groove, the body and claws beingmade of a single piece of metal.

,3. A'shoe-nail for mountain boots, comprising in combination, a bodyhaving the general shape of a T, adapted to be placed under the sole ofthe boot on the edge of the latter, and the transversebranchof whichembraces in ageneral manner the contour of said edge, at least oneelongated claw located on said transverse branch, two

elongated claws located on the longitudinal branch of said body andconsequently havin quite. different directions from that of the firstclaw, and being separated from the latter and from each other by adistance at least equal to the height of the highest of the three claws,and the shoe-nail having at least one pair of holes adapted to receivethe lateral branches of a .U-shaped afixing staple the lateralbranchesof which penetrate into the sole, and being'provided withagroove'between the holes of a pair of holes so that the transversebranch of the staple can be at least partially received insaid groove,said shoe-nail being .further provided with a passage ending in thegroove so thata tool may-be introduced under the transverse branch toextract the staple, the body and'claws being made of a single piece ofmetal. u r
